The Lowdown
Alright, let’s get this straight: the next two weeks aren’t exactly lighting up the coast around here. We’re in a pretty quiet spell, and there’s nothing to get too fired up about for a good while. You’re looking at a solid stretch of days with hardly anything worth paddling out for, especially through the end of August and into the first week of September.
The first time we see anything that might even qualify as surf is on Wednesday, September 2nd. That morning, Kennebunk Beach is showing a small, weak swell – around 4ft from the southeast. The period is short at 6 seconds, so it’s disorganised, but the wind is clean, coming cross-offshore out of the ESE. The combined energy is still only moderate (183). It’s surfable, but just barely, and only for intermediates who don’t mind very ordinary conditions. The afternoon is about the same, still 4ft, with a little more energy (189), but it’s nothing to write home about.
Thursday the 3rd sees a bump in size – 5ft to 6ft – but that’s paired with a moderate breeze out of the SE and E, making for messy, choppy conditions in the morning. The afternoon cleans up a bit, but the swell is still short period (6-7 seconds) and the energy is moderate (269). Honestly, even with the clean wind, the quality isn’t there for a good session.
After that, it drops off fast. Friday the 4th through to Sunday the 13th is a long stretch of tiny, weak surf – mostly 1ft to 4ft – with periods mostly short and combined energy values rarely breaking 100. There’s a few glassy moments on the 5th and the 13th, but with hardly any swell, it’s just a flat, pretty surface.
The only other blip is on Sunday afternoon, September 13th. That shows a 5ft south swell with a short 6-second period, but surprisingly glassy conditions with light wind. Combined energy jumps to moderate (145). It’s the most interesting offering in the whole forecast, but it’s still only “surfable but ordinary.” For a sheltered spot like Kennebunk Beach, which prefers ENE swell, this south pulse isn’t ideal.
Bottom line: there’s no standout session here. The best bets are the very ordinary, clean windows on September 2nd and maybe the glassy afternoon of September 13th, but keep expectations low. Kennebunk Beach (Maine) just doesn’t have the juice this time around.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
